Sigma 20mm f/2 DG Contemporary Lens Black for Sony E Summary
The Sigma 20mm f/2 DG Contemporary Lens Black for Sony E is a compact full-frame ultra-wide prime lens for Sony E-mount mirrorless cameras. It is from Sigma’s Contemporary I Series, which is a range of small, robust primes with great handling and high optical performance.
At 20mm, it captures a wide field of view that suits landscapes, interiors, architecture, weddings and astro, while still being easy to carry all day long. The f/2 aperture is excellent in low light and allows for handheld shooting when required. It focuses down to 22cm with 1:6.7 magnification, which is useful for closer compositions and wide-angle perspectives.
This as one of two 20mm options for mirrorless users from Sigma. It is considerably smaller and lighter than the 20mm f/1.4 DG DN Art, while still delivering very high image quality. The f/1.4 Art lens brings a wider aperture and more advanced features, but is also larger and heavier.

Sigma 20mm f/2 DG Contemporary Lens Black for Sony E in More Detail
Optical and image quality
The 20mm focal length of this lens gives a wide perspective that suits big scenes and interiors, which makes a good choice for interiors, architecture, and landscapes where edge detail is important. Image rendering is consistent across the frame, with good control of aberrations and high levels of sharpness even at wider apertures.
The optical design uses 13 elements in 11 groups, including three glass-moulded aspherical elements, one SLD element and one FLD element. This layout helps control chromatic aberration with clean detail across the image. Sigma also includes coatings to reduce flare and ghosting when shooting in bright light or strong backlight.
Autofocus operation
Autofocus is quick, quiet and accurate, which suits stills and video. The lens includes an AF and MF switch on the barrel for manual focus control. Internal focusing keeps the lens length consistent while focusing, which helps when working close to a subject or using a stabiliser.
Video
For video, the lens stays compact and balanced, which helps on handheld rigs and gimbals. The wide focal length is useful for walk-and-talk filming, interiors and establishing shots. Focus changes stay controlled, and coatings help keep contrast when shooting into strong light sources.
Handling and controls
This lens follows the I Series approach with an all-metal build, an aperture ring and knurled control surfaces for a firm grip. The mount uses coated brass for strength and includes a rubber seal to help keep out dust and moisture.
A water and oil repellent coating on the front element helps when shooting in poor weather or near sea spray. The lens also accepts standard 62mm filters, which is useful for ND, ND grad and polarising filters, particularly for landscape work.
Two 20mm options for mirrorless
Sigma describes the 20mm f/2 DG Contemporary as considerably smaller and lighter than the 20mm f/1.4 DG DN Art, while delivering comparable image quality. The f/1.4 Art lens offers a wider aperture and more advanced features, but with a larger build.
Frequently asked questions
